Gov. Bill Haslam has vetoed a bill that would have required state insurance plans to cover an experimental cancer treatment, WPLN reports. The treatment is called proton therapy, and it’s designed to do less damage to the body than average cancer treatment, but providers say it’s too expensive and unproven. The governor said that the mandate “could put patients at risk and expose them to excessive charges from out-of-network providers.”

The Memphis Veterans Affairs Medical Center’s director said yesterday he would immediately launch an investigation into “serious allegations” that a recently promoted official falsified time cards of hospital employees, The Commercial Appeal reports. The claim is that Cheryl Brewer, assistant chief of the human resources office, approved paid time off for employees who had already used their annual leave. This newest incident joins a list of troubles that have plagued the facility in recent months, including the firing of two top officials and increased scrutiny from Tennessee’s Congressional delegation.
